Lord 2 Api - Custom field on Item not updating in ECC

Hi All

I have a customer field in erp that I need to get populated from crm.

I have added the field to the additional data b section in vao1.

I have added the field to the TDS_ITEM_COMC and  TDS_ITEM_COMV

I have added the screen to the lord mapping table under ITEM, and I have have enabled "Automatic Field Transport".

I have updated the badi BADI_LORD_DO_PAI method Add_supply_LIST with the following code

IF iv_object_id EQ 'ITEM'.

     CLEAR ls_supply.

     ls_supply-field = 'ZZADTV'.

     ls_supply-check = 'N'.

     APPEND ls_supply TO ct_supply.

   ENDIF.

My field is being populated from CRM and is being passed through to r3.  I know this because I debugged  the function module erp_lord_get_item_multi

and I can see the correct value for my field, and there are no errors reported.

Any one got any ideas.

I have done this for a customer field on at header level and it works.

Thanks

Darren
